will supply the inertial measurement solution for the Raytheon
Joint Precision Approach and Landing Systems (JPALS) Shipboard Reference program. Under this contract, Northrop Grumman
's Navigation Systems Division will deliver 18 LN-270 inertial navigation systems (INS) for the engineering and manufacturing development phase of the JPALS Increment 1A Shipboard Reference System (SRS). Future production orders are anticipated to be considerable. The first LN-270 unit will be delivered in early 2011. JPALS is an all-weather, all-mission, all-user landing system based on local area differential Global Positioning System (GPS). JPALS works with GPS to provide accurate, reliable, landing guidance for fixed and rotary wing aircraft and supports fixed-base, tactical, and shipboard applications. For the SRS, each JPALS-equipped ship will employ three Northrop Grumman fiber optic gyro-based LN-270 INS units to measure the ship's motion.
